我国启动国际地月立方星座大科学计划

中国正式启动国际地月立方星座大科学计划，将在地月空间部署卫星群进行系统性观测1。该计划涉及部署30颗不超过30公斤的12U立方星，分6批送至1∶3地月共振大椭圆轨道，观测范围从地球低轨道延伸至距地球约200万公里的地月空间1。按照初步安排，全部卫星发射部署预计在2030年左右完成1。

计划的科研目标包括空间环境监测、伽马射线暴探测和月球资源勘探1。其中伽马射线暴定位精度将提升至亚角秒级1。中方将统一研制高能粒子成像、空间磁强计、伽马射线暴探测三套标准载荷，并免费向合作方提供1。

该项目采用联合设计、免费搭载、经费各担、科学数据共享的国际合作原则1。泰国、塞尔维亚、埃及、塞内加尔、印度尼西亚等多国科研机构已加入该计划1。目前第一阶段工程研制已启动，卫星、载荷、测控等大系统总体方案论证即将完成1。国际深空探测学会副理事长胡朝斌表示，"我们期待和全球伙伴一道，共同拓展人类对深空宇宙的认知边界"1。

China has formally initiated an international megascience program to deploy a constellation of cube satellites throughout Earth-Moon space for systematic observation 1. The initiative will position 30 CubeSats, each weighing no more than 30 kilograms, across six deployment phases into 1:3 Earth-Moon resonant orbits, with full satellite deployment targeted for completion around 2030 1. The observation zone extends from low Earth orbit to approximately 2 million kilometers from Earth 1.

The mission objectives encompass space environment monitoring, gamma-ray burst detection with positioning precision enhanced to sub-arcsecond levels, and lunar resource exploration 1. China will develop and provide free access to three standardized instrument payloads—high-energy particle imaging systems, space magnetometers, and gamma-ray burst detectors—to participating nations 1. The program operates under principles of joint design, free rideshare opportunities, cost-sharing, and open scientific data sharing 1.

Multiple nations have joined the collaborative effort, including Thailand, Serbia, Egypt, Senegal, and Indonesia 1. The initial phase of engineering development is underway, with comprehensive system verification for satellites, payloads, and tracking systems nearing completion 1. According to Hu Chaobin, Vice President of the International Deep Space Exploration Society, "We look forward to working with global partners to jointly expand humanity's understanding of the deep cosmos" 1.
